【摘要】：射频识别(Radio Frequency Identification,RFID)技术的出现可追溯至20世纪40年代,经过相当时间的发展,于20世纪90年代兴起。作为自动识别技术的一种,被誉为21世纪最具创造性和发展前景的信息技术。近年来随着信息社会的不断发展,RFID技术正扮演着愈发重要的角色。超高频(Ultra High Frequency,UHF)RFID技术,作为RFID技术中的一员,工作在射频频段,具有高速传输、远距离多目标识别等优势,目前已经成为国内外研究和应用的热点,在未来势必成为信息社会的重要组成部分。传统的ASIC系统芯片的设计,需要较长的研发周期以及较大的成本,随着微电子技术的不断发展,半导体工艺的不断革新,以及市场需求所带来的冲击力,传统的设计流程已难以跟上步伐。因此,基于IP(Intellectual Property)核的SoC(System on Chip)设计方法开始流行。SoC技术可以有效集成多个IP核,实现复杂的系统功能,同时可以较好地降低功耗、尺寸等关键因素,加快产品的研发周期,降低研发成本,逐渐成为集成电路设计的重要方向之一。本文基于ISO/IEC 18000-6C协议,采用SoC的设计方法,划分软硬件模块,采取软硬件协同设计的方法设计了UHF RFID系统的数字基带处理单元。选取开源处理器MC8051,采用Verilog硬件描述语言设计完成UHF RFID基带通信链路模块,并通过WISHBONE总线协议将其作为独立的IP核与MC8051互连,实现系统硬件的设计,并在MC8051中完成协议部分算法的实现,最终实现阅读器与标签基带的通信,完成系统的验证。
[Abstract]:RFID (Radio Frequency Identification (Radio Frequency Identification,RFID) technology can be traced back to the 1940s. After a long period of development, it rose in the 1990s. As a kind of automatic recognition technology, it is praised as the most creative and developing information technology in the 21st century. In recent years, with the development of information society, RFID technology is playing an increasingly important role. UHF (Ultra High Frequency,UHF) RFID technology, as a member of RFID technology, works in RF frequency band, has the advantages of high speed transmission, long distance and multi-target recognition, and has become a hot spot of research and application at home and abroad. In the future is bound to become an important part of the information society. The design of traditional ASIC system chips requires a long research and development cycle and a large cost. With the development of microelectronics technology, the continuous innovation of semiconductor technology, and the impact of market demand, The traditional design process has been difficult to keep up with the pace. Therefore, the SoC (System on Chip) design method based on IP (Intellectual Property) kernel is becoming popular. SoC technology can effectively integrate multiple IP cores, realize complex system functions, and reduce power consumption, size and other key factors. Speeding up the R & D cycle of products and reducing R & D costs are becoming one of the important directions of IC design. Based on the ISO/IEC 18000-6C protocol, the design method of SoC is used to divide the software and hardware modules, and the digital baseband processing unit of the UHF RFID system is designed by the method of hardware / software co-design. The open source processor MC8051, is selected to design the UHF RFID baseband communication link module with Verilog hardware description language, and it is interlinked with MC8051 as an independent IP core through WISHBONE bus protocol to realize the hardware design of the system. Finally, the communication between reader and tag baseband is realized, and the verification of the system is completed.
